I think awk has a reasonable learning curve, especially to new users, so its good to see examples of awk. Especially since this is where awk shines.
Here is the awk way:
( print the first field of any line that does not have a pound sign in it. )
awk -F: '!/#/ { print $1 }' /etc/passwd
(print lines where a comment does not exist in field 1)
awk -F: '$1 !~ /#/ { print $1 }' /etc/passwd
